Testing with authorisation directive

[npabllla]

Hello,
I use netflix-dgs-authorisation-directive in my app and want to test mutations which annotated with @secured .

When I'm trying test it like regular mutation without @secured I get exception

java.lang.ClassCastException: class com.netflix.graphql.dgs.internal.DgsWebMvcRequestData cannot be cast to class test.com.config.GraphQLContext

GraphQLContext - it's my custom class for context, so decided mock DgsContext, but it was unsuccessful, also I tried mock GqlContextBuilder and DgsWebMvcRequestData, but it also was unsuccessful.

Also I looked for best practice for testing with authorisation directives in dgs docs but there nothing about that.
May be there is somewhere best practice or examples of such test ?
